Practical Quantum Cryptography and Possible Attacks
Google Tech Talks
January, 24 2008
Quantum cryptography is actually about secure distribution of an encryption key between two parties. In this talk I give an introduction to practical quantum cryptography. I will describe the technical details of a few implementations, how the security of the distributed key might be compromised, and what steps can be taken to prevent this.
Speaker: Alexander Ling
Alexander Ling is a graduate student with the Experimental Quantum Optics group in the Center for Quantum Technologies in Singapore. He has spent the last four years building sources of high-quality polarization-entangled photon-pairs. The entangled light is then used for various things like testing the validity of quantum mechanics and quantum key distribution.
He hopes to complete his Ph.D. in 4 months.
